Definitions

  • the present technology relates to the field of hearing aid devices. More particularly, it relates to a method for adjusting a hearing aid device and a system for carrying out the method.
  • the method and the system are based on the principle of augmented reality.
  • a hearing aid device is a device for aiding an individual in regard to his or her hearing. It may be a hearing prosthesis for compensating a hearing loss, namely an acoustic hearing aid for amplifying sound. Hearing aid devices need to be adjusted to the needs and preferences of their users. The adjustment can be done based on an audiogram by a so-called pre-calculation with a fitting formula. On top of that there can be a so-called fine-tuning. The adjustment can be done by a professional or by the user himself. The adjustment by the professional has the advantage that expensive equipment and more expertise is available. The adjustment by the user has the advantage that it is less expensive and can be done directly in the real-world situation for which it is intended for.
  • Augmented reality is known from applications in military, video games, navigation, healthcare and many others.
  • a game based on augmented reality which is particularly popular is "Pokemon Go”.
  • the WO 2014 / 1990086 A2 by Edwards discloses an augmented reality system for use by hearing impaired people.
  • the user is provided with additional visual and auditory information such the name of a person.
  • the WO 2015 / 017007 A1 by Pruthi discloses the integration of hearing aids with smart glasses to improve the intelligibility in noise.
  • the WO 2008 / 025858 A2 by Boretzki discloses a method for fitting hearing aids by presenting audiovisual scenes comprising sound objects.
  • the sound objects can be selected to perform specific tuning tasks.
  • the DE 10 20014 / 218832 A1 by Eckl discloses a method for adjusting a hearing aid using smart glasses. Adjustment parameters are determined based on optical information of a camera.
  • the method of claim 2 is advantageous in that adding at least one virtual sound object allows the adjustment even if an essential sound, such as a primary speaker, is currently missing in the real world.
  • the method of claim 4 is advantageous in that adding at least two virtual sound objects allows to find good solutions for tradeoffs, when an adjustment should be valid for multiple sounds.
  • the method of claim 5 is advantageous in that associating sound processing parameters with virtual sound objects allows an efficient target-oriented adjustment of multiple parameters.
  • the method of claim 6 is advantageous in that virtual sound objects having a virtual location in the real-world environment open up the possibility of a sound parkours. The user may walk through the room and discover different virtual sound objects for specific adjustment tasks.
  • the method of claim 7 is advantageous in that allowing to add, move and delete the virtual sound objects makes the procedure more interactive and entertaining. This feature may also be part of a game.
  • the method of claim 8 is advantageous in that combining real-world sound objects with virtual environments allows adjustments of noisy situations, such as in a restaurant, even though the user is currently in a quiet situation.
  • Fig. 1 is a schematic view of a user, an environment and devices according to the present technology.
  • the user 1 is wearing at least one hearing aid device 2. He or she is holding a smartphone 3 such that the camera of it is viewing a real-world environment 11, namely a tree.
  • the image or video feed of the camera is augmented with a virtual sound object 12, namely a bird.
  • the sound of the real-world-environment is combined with the virtual sound of the bird.
  • the user listens to the combined sound via the at least one hearing aid device 2 and adjusts a sound processing parameter of the hearing aid devices 2 with a user control 4.
  • Fig. 2 is a schematic view, similar to the one of Fig.1 .
  • the camera is viewing a real-world sound object 21, namely a bird, which is then augmented with a virtual environment 22, namely a tree.
  • the real-world sound object 21 may be in front of a special background 23, in particular a green or blue screen. This facilitates that suppression of the real-world background 23.
  • a special background 23 in particular a green or blue screen.
  • Fig. 3 is a diagram illustrating the method for adjusting at least one hearing aid device according to the present technology.
  • a real-world image or video 34 is recorded thereby producing a real-world recording 33.
  • the real-world recording is augmented by adding an augmentation 35 and/or 36 thereby obtaining an augmented recording 37.
  • the augmentation 35 is a virtual sound object (case of Fig. 1 ).
  • the augmentation 36 is a virtual environment (case of Fig. 2 ).
  • the augmented recording 37 is presented to the user.
  • at least one sound processing parameter is adjusted by the user using at least one user control.
  • the hearing aid devices are used in daily life. All or some of the steps may be carried out simultaneously.
  • Augmented reality A real world environment is enhanced by computer-generated perceptual information. According to the present technology, the perception at least in regard to the sense of hearing is enhanced. Optionally, also the visual perception is enhanced. This is different from virtual reality, where there is substantially only computer-generate perceptual information presented to the user.

  • Adjustment parkours There may be an adjustment of multiple sound processing parameters incorporating multiple virtual sound objects and/or virtual environments. The user may be guided through such a parkours. Performing adjustment tasks in the way of an adjustment parkours may be especially advantageous in case of children which have a generally smaller attention span. The list of tasks to be completed may be defined by a hearing care professional.
